A yau, Ina so in raba tare da ku bambanci tsakanin epoxy gilashin fiber allo da PTFE board, to bari mu dubi shi tare.

Da farko, muna bukatar mu san abin da epoxy gilashin fiber jirgin da PTFE jirgin ne.

An raba faranti na PTFE zuwa nau’i biyu: faranti da aka ƙera da faranti. An yi faranti da aka ƙera da resin polytetrafluoroethylene ta hanyar yin gyare-gyare a cikin zafin jiki, sa’an nan kuma a sanyaya su. An yi allon juyawa da guduro na PTFE ta hanyar latsawa, ƙwanƙwasa, da bawo. Akwai nau’ikan faranti guda biyu na PTFE: faranti da aka ƙera da faranti. Ana yin faranti da aka ƙera da resin polytetrafluoroethylene ta hanyar yin gyare-gyare a cikin zafin jiki, sa’an nan kuma a sanyaya su. An yi allon juyawa da guduro na PTFE ta hanyar latsawa, ƙwanƙwasa, da bawo. High zafin jiki juriya har zuwa 250 ℃, low zazzabi juriya -196 ℃, lalata juriya, weather juriya, high lubrication, ba mannewa da sauran halaye. Sai dai narkakken alkali karfe, farantin PTFE da kyar ya lalace ta kowace sinadari. Misali, a cikin sinadarin sulfuric acid, nitric acid, hydrochloric acid, ko ma tafasasshen ruwa a cikin ruwa, nauyinsa da aikinsa ba ya canzawa, kuma kusan ba ya narkewa a cikin dukkan abubuwan kaushi.

Epoxy gilashin fiber allon kuma ana kiransa epoxy gilashin fiber allo, epoxy phenolic laminated gilashin allon allon, epoxy guduro yana nufin kwayoyin polymer fili dauke da biyu ko fiye epoxy kungiyoyin a cikin kwayoyin. Dangantakar kwayoyin halitta ba ta da girma. Tsarin kwayoyin halitta na resin epoxy yana da alaƙa da ƙungiyar epoxy mai aiki a cikin sarkar kwayoyin halitta. Ƙungiyar epoxy na iya kasancewa a ƙarshe, a tsakiya ko a cikin tsarin tsarin sarkar kwayoyin halitta. Saboda tsarin kwayoyin halitta ya ƙunshi ƙungiyoyin epoxy masu aiki, za su iya fuskantar halayen haɗin kai tare da nau’ikan nau’ikan magunguna daban-daban don samar da polymers marasa narkewa da infusible tare da tsarin hanyar sadarwa ta hanyoyi uku.

To, menene bambanci tsakanin epoxy gilashin fiber jirgin da PTFE jirgin?

Jirgin PTFE an yi shi ne daga resin polytetrafluoroethylene ta hanyar tsari na musamman kamar gyare-gyare, matsa lamba na hydraulic, juyawa, da dai sauransu Ayyukansa na iya tsayayya da yanayin zafi na 260 digiri. The epoxy gilashin fiber jirgin da aka yi da gilashin fiber impregnated da epoxy guduro manne da curing wakili. , Matsakaicin zafin jiki yana da kimanin digiri 100, kwamitin PTFE zai iya tsayayya da kowane acid da alkali, kuma epoxy yana jin tsoron acid mai karfi. Daga mahangar rabe-raben filastik, na farko yana cikin filastik thermoplastic, na biyun kuma yana cikin filastik thermosetting. The epoxy gilashin fiber allo yana da babban ƙarfi a dakin zafin jiki.
